Cancer of the lip arises as a small lump, like a wart generally, on the lower lip in men from forty to seventy. Sometimes it appears at first simply as a slight sore or crack which repeatedly scabs over but does not heal. Its growth is very slow and it may seem like a trivial matter, but any sore on the lower lip in a man of middle age or over, which persists, should demand the immediate attention of a surgeon, because early removal is more successful in cancer of the lip than in any other form.
